My machine (Janome Mystyle 22) is too elderly/simple for duel feed, so I have to do it for it
Once I place the matched up pieces under the foot and take the first couple of stitches, with the needle down (by hand, usually) I then make sure that the end pieces are lined up and hold onto both of them tightly together, if there is any discrepency, I add a little bit of tension and stretch them so that they match in length, then I continue sewing.
My maths for the sashing etc has been coming along, and I have found the perfect green to go with my yellow/orange/reds, bought on a whim, when I bought the blue skirt batik, the down side is that I have only one metre (40") and for my planned patterning I have
absolutely no spare for mis-cuts, and I am trying to work out how much I have for a little sashing around the mini blocks.
